Commands
*TST? (Test)
The *TST query starts a self-test on the instrument.
The *TST? query causes the WDCA to perform a self-test, and places a
response in the output queue indicating whether or not the self-test com-
pleted without any detected errors. This includes a self-test of the TLS (tun-
able laser source). Use the :SYSTem:ERRor command to check for errors. A
zero indicates that the test passed and a non-zero indicates the self-test failed.
Disconnect Inputs First
You must disconnect all front-panel inputs before sending the *TST? query.
If a test fails, refer to the troubleshooting section of the service guide.
The Self-Test takes approximately 3 minutes to complete. When using time-
outs in your program, 200 seconds duration is recommended.
